This invention relates to an apparatus for gradually decreasing the temperature of wa ter discharged from a mixing-vessel by nozzles or faucets, so that the bather is subjected to the salutary action of water that cools uniformly and by imperceptible stages.

In the accompanying drawings, Figure 1 is a longitudinal section of my improved apparatus Fig. 2, a cross-section on line B B, Fig. 1; Fig. 3, a cross-section on line S S, Fig. 1; Fig. 4, a longitudinalsection through a modification; Fig. 5, a cross-section of the apparatus, showing two cold-water inlets; Fig. 6, a longitudinal section of a modification of the apparatus; Fig. 7, a plan thereof; Fig. 8, a longitudinal section of a further modification, and Fig. 9 a plan thereof.

The letter A represents a vessel adapted for the reception or generation of warm water. The warm water may be either conducted into the apparatus through a pipe 0, Fig. 4, or a fireplace B is formed in the lower part of the vessel to warm the water poured or fed into the same. WVith the vessel A there also communicate one or more cold-water-inlet pipes a and a mixed-water-exit pipe m that leads to a nozzle, faucet, hose or other discharging device. 7

Within the vessel A there is free to revolve a mixing-cone K, turning around spindle K No. 5,845; in Belgium September 2, 1892,1T0. 101,217, and

and provided with slits b and a series of radially-projecting mixing-blades b. At its lower end the cone K is furthermore provided with paddles or buckets k to constitute a turbine. These buckets receive the impact of the cold water admitted by tube a, which thus serves to revolve the turbine. To aid the operation of the mixing-cone, a series of blades or ribs 0 project inwardly from the inner face of vessel A.

In use the water discharged through pipe m will be at its highest temperature at the time the cold-water supply of pipe ais turned on. Then the cold water will be gradually and thoroughly mixed with the hot water within vessel A to gradually and uniformly decrease the temperature of the water discharged. Thus the bather will be subjected to the desirable action of Water cooling at any desired rate but always uniformly. A thermometer P may be used to note the gradual decline of temperature.

. In Fig. 4 two cones K are shown to be contained within vessel A, such construction being useful where the invention is to be applied on a larger scale.

In Figs. 6 and 7 the cone is inverted, pointing with its apex downward, and there secured to a disk carrying the buckets is.

In Figs. 8 and 9 the cone-wheel is replaced by a revolving nozzle D, the bent and perforated arms f of which communicate with the cold-water-supply pipe a.

What I claim is- The combination of a vessel having inwardly projecting blades 0, with a cold water supply, a hot water supply, a mixed water discharge and a slitted revoluble mixer provided with mixing blades and buckets, substantially as specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

MAX BIERMANN.
